The body of a 38-year-old man was pulled Monday evening from Lake Ray Roberts, officials said.

The Fort Worth man had been in the water at the swim beach in the park's Isle du Bois area when he went underwater. His body was recovered with the help of sonar equipment about 6 p.m., said Capt. Cliff Swofford with the Texas Parks and Wildlife Department.

The Denton County sheriff's office, Denton Fire Marshal deputies, state park police and the Pilot Point Fire Department assisted in the effort.
